The present inventiozr is directed to guiding devices for fabric duringthe course of sewing operations, and more particularly to a device whichrenders it feasible to sew or hem both edges of a piece of fabricat thesame time; In the production of various articles on a com mercial scale,it becomes necessary to sew or hem both edges of a relatively long stripof fabric.

l Po-accomplish this; it has become customary to:

pass the fabric; through suitable folders and thenthrough the sewingmachine in order'to hem one of the edges thereof? 7 Then it wasnecessaryto fold or r011 the sewed fabric and then pass the sameal-gainthroughthe' -sewi'ng machine in a similar manner in orderto-hemthe opposite edge thereof. Y Y

attempts have'been' made to conduct the; operationas a: sing-1e unit bypassing the fabric" reclaims; (01. 112- 152 tical" angle members 5 and'6 secured to mem her 1 below bed i of the machine. Members 5' and 6constitute a frame on which theguiding' device is mounted. It includes arod 8 at the lower end of angles 5 and 6 placed in a position which isat" a small or acute angle to t-he horizontal; One end of rod 8 passesthrough through the sewing machine tosew bothedges attire same time.However, such attempts have failed'beeause of various difiicultie'swhich render it impossible to accomplish the" same.- The presentinvention seeks to overcome suchdiffic'ulf ties and disadvantages andtoprovide a method of sewing. fabric and a' de'vice tor -accomplish;mgthe purpose,- whereby: a-g-singlje passage of the fabric throughtheedgesthereoi' I w v i V It also among the objectsof the presentinventionto" provide a device which isI-si-mple in character and which may beattached to amachine will sew both standard. sewing machine; said deviceacting" as a: guide and accomplishing: the" desired-results;

There isprovided the usual sewing. machine having a--base or bed- I anda sewin head 2 having a'pair of needles 3 and 4 therein? None of themechanism of the sewing machine is illustrated or. described andsai'dmachine operates as usual."

At the front ofthe base i are a pair' of ver-' opening 3 in angle E andis heldin position by nuts in. A slot H' in angle 5- is provided at thelower end thereof. The free end of rod ii passes through slot If andanut [2' is threaded on the end of said rod whereby the same may beclamped in any one of a plurality of positions, as shown: in Fig; 1 Justabove rod dis a pair of horizontal parallel bars l t secured: betweenend members-- it and? having threaded rods #5 passing through openingsin angles 5 and t2 Nuts 16 some as means for clampingthe same to theframe; r

Above the pivoted bars: are a series of four horizontarfixedbarsi- Ll;the ends of which pass through openings'in-angles 5 and 6 and the rodsHt fits over rods ti in: vertical position approximately centrally ofsaid rods. Movable guide plates t9: and were mounted on either side ofplate "3- and; a thread and nut arrangement 21:

and 22 is provided lior clamping plates l9 and 20' in adjustedpositions;

Above the fixed bars there is mounted a fixed rod 23 between angles 5and 6. A pairof swinging' bars 24 in a: horizontal position is mountedon:v end members" 25;. the latter being loosely mounted on red 23;-Thereby the frame just.

formed is; adapted to swing. Two such swinging framesareprovidedeachbeing on one side of the center OfeI'0df23L-f Y 7 At the topof angles 5" and 8 is secureda rod 26 having mounted thereon a pair ofwheels 2! whichzareiprovided with convexiaces, bosses 23 having setscrews therein; providing means for fi-xingpthe positiorrof said wheelson-rod Zfi.

The-frame and, its associated guide parts are so mounted that the centerline thereof is approximately between needles 3 and t. Folders orhemming attachments 29 are secured to basewheel 21 and folder 29 asindicated at 35. It then passes under needle 3 as shown at 36 so thatthe other side of the fabric is hemmed.

The inclination of rod 8 from the horizontal gives asufficient angle tothe fabric as it passes around the same to cause it to travel parallelto V fabric and a proper positioning thereof ,in the sewing machine isobtained. Depending upon the width of the cloth will depend the angle ofrod 8. It may be adjusted to various angles based upon the type offabric, its width and other factors. Pivoted bars l3fmay be held in aposition where practically no tension is exerted on either of the pliesof fabric passing through the same. If desired, bars l3 may be twistedinto one position or the opposite one so as to exert tension on theother of said plies.

Guide plates l9 and 20 may be adjusted lateral] on bars I! so that theyprevent the fabric from moving from side to side and thus insurea propermovement of the fabric into the needles. Wheels 2'! need not necessarilybe rotatable and their position may be other than shown at the top. ofthe guide frame. entirely omitted.

Although the invention has been described set-. ting forth a singleembodiment thereof, it will be apparent to those skilled in the art thatvarious changes in the details and construction may be made within thespirit of the invention- The guide frame need not be made of angles butmay be made of other structural shapes and the several bars and rods maybe held therein differently than shown. Some of the bars may be omittedor others may be added to givedecreased or increased efiects. Variousmaterials of construction as are well known may be employed. These andother changes may be made without departing from the spirit of theinventionpthe scope of which is to be broadly constructed and not to belimited except by the character of the claims appended hereto.
